On a recent sunny walk around town, I spotted the first early spring crocus of the season, and on Main Street, the dirty giant mountains of old plowed snow have finally melted away. Even so, the cold dark nights and frosty mornings of late winter continue. Yes, despite our yearnings for spring, it is still most definitely sweater and casserole weather. This week, I turned to ground turkey to create an unexpected twist on an old favorite recipe, Shepherd's Pie. Filling the house with tempting aromas as it bubbled in the oven, the resulting dish was warm and welcoming on a chilly night.
